## Title
Relay processing device, communication terminal, relay processing system, relay processing method, and program

## Abstract

When a call from a call terminal to a called terminal is received, a relay processing device transmits calling terminal specific information that specifies the calling terminal to the called terminal by using data communication. The calling terminal specific information, for example, is a phone number of the calling terminal, but may be a user's name of the calling terminal. The called terminal transmits to the relay processing device, connection information that indicates whether or not to respond to the call from the calling terminal. The transmission of the connection information may be performed by any one of voice communication and data communication. The relay processing device connects the phone call between the called terminal and the calling terminal or cuts off the connection between the calling terminal and the relay processing device according to the connection information.

## Background
TECHNICAL FIELD
The present invention relates to a relay processing device relaying a phone call between a call terminal and a called terminal, a communication terminal, a relay processing system, a relay processing method, and a program.
BACKGROUND ART
Recently, a phone call between two communication terminals is performed through a relay processing device. Specifically, a call terminal calls using a phone number of the relay processing device as the phone number of a called terminal, and thus communication between the calling terminal and the relay processing device is established. Then, the relay processing device calls the called terminal, and thus communication between the relay processing device and the called terminal is established. The relay processing device relays the phone call between the calling terminal and the called terminal (for example, see Patent Document 1).
When relaying the calling terminal and the called terminal by using the relay processing device, there is a disadvantage that the phone number of the calling terminal is not transmitted to the called terminal, and thus it cannot be aware of which calling terminal has called. To solve this problem, Patent Document 2 discloses a system that performs the following process to confirm from which calling terminal the called terminal is receiving a call. Firstly, plural phone numbers are prepared, which are used when the relay processing device establishes communication with the called terminal. Then, a user of the called terminal allocates the phone numbers of terminals that may be the calling terminals to the respective phone numbers. The relay processing device determines which phone number is used to call the called terminal according to the allocation.

(First Embodiment)
FIG. 1 is a block diagram illustrating the configuration of a relay processing system 10 according to a first embodiment of the invention. The relay processing system 10 includes a called terminal 400 and a relay processing device 200. The relay processing device 200 relays a phone call from a call terminal 100 to the called terminal 400. The calling terminal 100 uses a first phone number of the relay processing device 200 as the a phone number of the called terminal 400. Further, the called terminal 400 is capable of performing both voice communication and data communication. The called terminal 400, for example, is a portable phone.
When the relay processing device 200 receives a call from the calling terminal 100 to the called terminal 400, it transmits calling terminal specific information that specifies the calling terminal 100 to the called terminal 400 by using data communication. The calling terminal specific information, for example, is the phone number of the calling terminal 100, but may be a user's name of the calling terminal 100. The called terminal 400 transmits to the relay processing device 200, connection information that indicates whether or not to respond to the call from the calling terminal 100. The transmission of the connection information may be performed by any one of voice communication and data communication. The relay processing device 200 connects the phone call between the called terminal 400 and the calling terminal 100 or cuts off the connection between the calling terminal 100 and the relay processing device 200 according to the connection information. Hereinafter, this will be described in detail.
FIG. 2 is a block diagram illustrating the functional configuration of a relay processing device 200. The relay processing device 200 includes a relay processing unit 210, a phone number storage unit 220, and a called information transmission unit 230.
The relay processing unit 210 receives first call information from the calling terminal 100. The first call information includes a first phone number and the phone number of the calling terminal 100. Further, the relay processing unit 210 functions as a connection information reception unit. That is, the relay processing unit 210 receives connection information after the called information transmission unit 230 transmits called information to the called terminal 400. Then, the relay processing unit 210 connects the phone call between the called terminal 400 and the calling terminal 100 or cuts off the connection between the calling terminal 100 and the relay processing device 200 according to the connection information.
The phone number storage unit 220 stores the first phone number and called terminal specific information that specifies the called terminal 400 so as to correspond to each other. The called terminal specific information, for example, may be the phone number of the called terminal 400 or an e-mail address.

The called terminal 400 includes a called information reception unit 410, a display unit (notification unit) 420, a response information acquisition unit 430, and a call processing unit 440. The called information reception unit 410 receives the called information from the relay processing device 200 through data communication. The display unit 420 displays the calling terminal specific information to notify a user of the calling terminal specific information. The response information acquisition unit 430 acquires from the user, response information that indicates whether or not to accept the call from the calling terminal 100. This acquisition, for example, is performed through an input key (not illustrated) set in the called terminal processing unit (connection information transmission unit) 440 performs a call process. Further, the call processing unit 440 transmits to the relay processing device 200, the connection information that indicates whether or not to connect the call with the calling terminal 100 based on the response information.
In FIG. 4, the configuration of units that are relevant to the essence of the present invention will not be illustrated in the drawing. For example, a radio communication function unit, a speaker, a microphone, and the like, which are configurations of a typical telephone, are not illustrated. Each component of the called terminal 400 illustrated in FIG. 4 does not indicate the configuration of a hardware unit, but indicates a block of a functional unit. Each component of the called terminal 400 is realized by any combination of hardware and software based on a CPU of any computer, a memory, a program loaded in the memory for realizing the components in the drawing, a storage unit such as a hard disk that stores the program, and an interface for network connection. It will be understood by those skilled in the art that there are various modifications of the realization method and device.
FIG. 5 is a flowchart illustrating a first example of the operation of the relay processing system illustrated in FIG. 1. In the process illustrated in the drawing, the relay processing device 200 has a second phone number and a third phone number as phone numbers when receiving the call from the called terminal 400.
Further, the relay processing unit 210 of the relay processing device 200 receives second call information of the relay processing device 200 from the called terminal 400 as the connection information. The relay processing unit 210 connects the phone call between the called terminal 400 and the calling terminal 100 when the second call information is transmitted by using the second phone number, and cuts off the connection with the calling terminal 100 when the second call information is transmitted by using the third phone number. The second phone number and the third phone number may be included in the called information or may be stored in the called terminal 400 in advance. Hereinafter, this will be described in detail.
Firstly, a user of the calling terminal 100 inputs or selects the first phone number by intending the call from the calling terminal 100 to the called terminal 400. The calling terminal 100 performs a call process by using the first phone number of the relay processing device 200 and transmits the first call information to the relay processing device 200 (step S20).
When the first call information is received, the relay processing unit 210 of the relay processing device 200 sends the first phone number included in the first call information and the phone number of the calling terminal 100 to the called information transmission unit 230. The called information transmission unit 230 reads the called terminal phone number that corresponds to the first phone number from the phone number storage unit 220 (step S40). Then, the called information transmission unit 230 generates the called information (step S60), and transmits the called information to the called terminal 400 through a short message service (SNS) (step S80). The called information includes the phone number of the calling terminal 100. Here, if the phone number of the calling terminal 100 cannot be acquired, for example, if the calling terminal 100 is set to block a calling number, or is a public telephone, the called information includes a message such as “the calling number is blocked” or “unable to get the calling number” instead of the phone number of the calling terminal 100. In this embodiment of the invention, the called information includes the second phone number and the third phone number of the relay processing device 200.
When the called information is received, the called information reception unit 410 of the called terminal 400 reads the phone number of the calling terminal 100 included in the called information, and generates display data for performing display on a display unit 420 by using the phone number. Further, the called information reception unit 410 outputs the generated display data to the display unit 420 to make the display unit 420 perform the display (step S100). In this case, the called information reception unit 410 may inform the user of the call from the calling terminal 100 by using ringtones or the like.
The user confirms the display on the display unit 420, determines whether or not to respond to the call from the calling terminal 100, and inputs the phone number as response information. That is, the user inputs the second phone number when responding to the call and inputs the third phone number when rejecting the call. The response information acquisition unit 430 acquires the input phone number (step S120), and calls the relay processing device 200 by using the acquired phone number (step S140). In this case, the call information to be transmitted includes the called terminal phone number of the called terminal 400 in addition to the phone number of the relay processing device 200.
When the call information is received, the relay processing unit 210 of the relay processing device 200 determines which phone number is used to perform the call from the called terminal 400. When the calling is performed with the second phone number (“Yes” in step S160), the relay processing device 210 establishes communication with the called terminal 400 and the calling terminal 100, and performs the relay of the phone call between the calling terminal 100 and the called terminal 400 (step S200). When the call is performed with the third phone number (“No” in step S160), the relay processing device 210 cuts off the communication with the called terminal 400 and the calling terminal 100, and performs the process for a call rejection (step S180). In this case, the relay processing device 210 may transmit predetermined voice data to the calling terminal 100.
FIG. 6 is a flowchart illustrating a second example of the operation of the relay processing system illustrated in FIG. 1. The processing illustrated in the drawing is equal to that of the first example illustrated in FIG. 5 except for the point that the called information transmission unit 230 of the relay processing device 200 transmits the called information by using an e-mail.
That is, the called information transmission unit 230 reads an e-mail address that corresponds to the first phone number from the phone number storage unit 220 in step S40, and transmits the called information to the called terminal 400 by e-mail in step S80.
FIG. 7 is a diagram illustrating a first example of the display that is performed by the display unit 420 of the called terminal 400 in step S100 of FIGS. 5 and 6. In the example illustrated in the drawing, the display unit 420 displays the second phone number and the third phone number to select either one of them. The user can input the second phone number or the third phone number by selecting the second phone number or the third phone number.
FIG. 8 is a diagram illustrating a second example of the display that is performed by the display unit 420 of the called terminal 400 in step S100 of FIGS. 5 and 6. In the example illustrated in the drawing, the called terminal 400 can process HTML type data. The display unit 420 displays a response button selected when responding to the call from the calling terminal 100, and a rejection button selected when rejecting the call. The response information acquisition unit 430 of the called terminal 400 acquires the selection of the response button or the rejection button as the response information. Further, the call processing unit 440 calls the relay processing device 200 by using the second phone number when the user selects the response button, and calls the relay processing device 200 by using the third phone number when the user selects the rejection button.
Next, the operation and effect according to this embodiment of the invention will be described. In this embodiment, when the calling is made from the calling terminal 100 to the relay processing device 200, the relay processing device 200 transmits the called information to the called terminal 400 by using the data communication. The called information includes calling terminal specific information that specifies the calling terminal 100. Because of this, information for specifying the calling terminal 100 can be transmitted to the called terminal 400. Further, since any special data is not required, it is not necessary to expend effort in the maintenance of the data.
Also, since the second phone number and the third phone number are used as the response information, the called terminal 400 can transmit the response information through voice communication. Further, in the case of responding or rejecting, the process in the relay processing device 200 is simplified.
(Second Embodiment)

In this embodiment of the invention, in the same manner as in FIG. 6 according to the first embodiment of the invention, the called information may be transmitted by e-mail rather than by SNS.
Even by this embodiment of the invention, the same effect as that of the first embodiment can be obtained. Further, since the called information includes the user terminal of the calling terminal 100, the display unit 420 of the called terminal 400 can display the user information of the calling terminal 100 even if the called terminal 400 does not store phone book data.
(Third Embodiment)

The connection information reception unit 250 receives the connection information transmitted from the called terminal 400 through the data communication. Further, the connection information reception unit 250 analyzes the received connection information and instructs the relay processing unit 210 whether or not to perform a responding process or a cutoff process.
FIG. 14 is a block diagram illustrating the functional configuration of the called terminal 400 of the relay processing system 10 according to an embodiment of the invention. The called terminal 400 illustrated in the drawing has the same configuration as that of the relay processing device 200 according to the first or second embodiment of the invention except for the point that the called terminal 400 includes a connection information transmission unit 450 separately from the call processing unit 440.

First, the response information acquisition unit 430 of the called terminal 400 acquires information that indicates whether or not to respond to the call from the calling terminal 100, rather than the second phone number or the third phone number, from the user as the response information (S120), and sends the information to the connection information transmission unit 450. The connection information transmission unit 450 generates the connection information for data communication based on the acquired information, and transmits the generated connection information through the data communication (step S142).
The connection information reception unit 250 receives the connection information that is transmitted from the called terminal 400 through the data communication. Then, the connection information reception unit 250 analyzes the connection information and instructs the relay processing unit 210 whether or not to perform the responding process or cutoff process. The relay processing unit 210 determines whether or not to perform the relay process (step S200) or the cutoff process (step S180) according to the instruction from the connection information reception unit 250 (step S160). When performing the relay process, the relay unit 210 calls the called terminal 400 (step S200). Also, when performing the cutoff process, the relay unit 210 cuts off the communication with the calling terminal 100 (step S180).
In this embodiment of the invention, in the same manner as in FIG. 6 according to the first embodiment of the invention, the called information may be transmitted by e-mail rather than by SNS. Further, in the same manner as the second embodiment of the invention, the relay processing device 200 may include the user information storage unit 240.

The relay processing device 200 according to this embodiment is equal to that of the third embodiment of the invention except for the following points. Firstly, before the called information transmission unit 230 transmits the called information, the relay processing unit 210 of the relay processing device 200 calls the called terminal 400 to establish the phone call between the calling terminal 100 and the called terminal 400. Further, the called information transmission unit 230 performs the data communication of the called information with the called terminal 400 when receiving request information indicating that the called information is requested from the called terminal 400.
FIG. 17 is a block diagram illustrating the functional configuration of the called terminal 400 according to this embodiment of the invention. The called terminal 400 is equal to the called terminal 400 according to the third embodiment of the invention except for the following points.
Firstly, before the called information reception unit 410 receives the called information, the call processing unit 440 receives the call information for establishing the phone call with the calling terminal 100 from the relay processing device 200.
Further, the called terminal 400 includes a call notification processing unit 460 and a request information transmission unit 470. The call notification processing unit 460 performs the call notification process notifying a user that the call processing unit 440 has received the call information. The call notification process, for example, includes performance of a predetermined display on the display unit 420. The request information transmission unit 470 acquires information indicating that the called information is requested from the user. Further, the request information transmission unit 470 transmits the request information for requesting the called information to the relay processing device 200.
Further, the called information reception unit 410′ acquires the called information after the call notification processing unit 460 performs the call notification process.
FIG. 18 is a flowchart illustrating the operation of the relay processing system 10 according to this embodiment of the invention, and corresponds to FIG. 15 according to the third embodiment. The operation illustrated in the drawing is equal to the operation illustrated in FIG. 15 except for the followings.
Firstly, when the first call information is received from the calling terminal 100, the relay processing unit 210 of the relay processing device 200 calls the called terminal 400 to establish the phone call between the calling terminal 100 and the called terminal 400 (step S22). When the call from the relay processing device 200 is received, the call processing unit 440 of the called terminal 400 makes the call notification processing unit 460 perform the call notification process (step S24).
When responding to the call from the relay processing device 200, that is, when responding to the call from the calling terminal 100 (“Yes” in step S26), the user inputs information for responding to the call. In this case, the call processing unit 440 and the relay processing unit 210 of the relay processing device 200 establish the phone call between the calling terminal 100 and the called terminal 400 (step S200).
Further, when the user does not respond immediately to the call from the relay processing device 200, that is, to the call from the calling terminal 100 (“No” in step S26), the request information transmission unit 470 transmits the request information to the called information transmission unit 230 of the relay processing device 200 (step S28). For the transmission of the request information through the request information transmission unit 470 and the response through the called information transmission unit 230 (step S80), for example, HTTP may be used.
The processes in steps S40 to S120 are equal to those according to the third embodiment of the invention. When the response information acquired in step S120 indicates the response to the call (“Yes” in step S135), the called terminal 400 does not transmit the connection information, but responds to the call from the relay processing device 200 in the same manner as in step S26 since the calling has already been made from the relay processing device 200 to the called terminal 400 in step S22. Accordingly, the relay process is established (step S200).
Further, in the case where the response information indicates the rejection of the call (“No” in step S135), the called terminal 400 transmits the connection information (step S142). When the connection information is received (“Yes” in step S162), the relay processing unit 210 of the relay processing device 200 cuts off the communication with the calling terminal 100, and cancels the call to the called terminal 400 (step S180). In this embodiment of the invention, in the same manner as in FIG. 5 or 6 according to the first embodiment of the invention, the called information may be transmitted by SNS or e-mail.
Even in this embodiment of the invention, the same effect as in the third embodiment of the invention can be obtained. Further, when the user has selected to respond to the call in step S26, it is possible to shorten the time from the call of the calling terminal 100 to the start of the phone call.
Although the embodiments of the invention has been described with reference to the drawings, they are exemplary in the present invention, and thus various configurations may be adopted in addition to those as described above. For example, in the above-described embodiments of the invention, the processing options with respect to the call from the calling terminal 100 are only “response” and “rejection”. However, such options may include “hold”, “audio response”, and the like. When the relay processing device 200 is interpreted as a multifunctional private branch exchange (PBX), for example, in the relay process (step S200) of FIG. 18, the options can be realized by including necessary information in the request information transmitted in step S28 and calling a necessary function based on this information. When increasing the options in the first and second embodiments, it is sufficient when phone numbers for receiving the second call information from the called terminal 400 to the relay processing device 200 are prepared as, many as the number of options as the connection information.
This application is based on Japanese Patent Application (No. 2009-023003) filed on Feb. 3, 2009, the disclosure of which is incorporated herein by reference in its entirety.
